ROBUST FLIGHT CONTROL DESIGN WITH RESPECT TO DELAYS AND CONTROL EFFICIENCIES

This paper presents a methodology making it possible to design a robust flight control system for a highly flexible aircraft, with significant cross-coupling between flight mechanics and structural dynamics modes. Because of this coupling, an iterative algorithm is proposed to guarantee aeroelastic stabilization. The proposed method will solve the problem via an iterative quadratic optimization under linear inequality constraints. In the end, the algorithm will be applied to a civil aircraft control system in lateral flight.
